The object of myfinvention is to provide a road machine having bladesmade in sections and so constructed that theblades can be set to fit orcutan'ycrown or'c'urvature on 6 the road; to provide a road machine inwhich the blades can be usedas a cutting edge oras a drag; to provide aroad machine which-has several blades all working independently of eachother; to provide road machine ad i 10 justable to any width of road; toprovide a roadm'achine which is portable and can be quickly dismantledso as to be transported from one section to another; to provide a roadmachine which has a hitching device at each end; and to provide a roadmachine which can be constructed of-either wood or metal and which isnormally mounted on runners but which can be mounted on- Wheels. Iattain-"theseandother objects ofi'ny invention by the mechanismillustrated in the accompanying drawings, in which,

Referring to theaccompanying drawings, I provide longitudinal side beams'l' and 3,

anda longitudinal central beam 2 to which are bolted the cross beams 7which have their reduced ends 10, as shown in Fig 6, mounted in thehollow metal housings 9; as shown in Figs. 7 and 8, these housings beingsuitably fastened to the beams by the angle plates 17. :15 providesuitable cross beams 4 as shown in 1g. 3. l V V i i H V The cross beams7 are reinforced by the tapered reinforcing bars 8, as shown in Fig. 1.I provide diagonal cross strips 5 and short diagonal strips 6 forming asort of lattice ends 'of'the members bolted, as by bolts 20, to thelongitudinal "beams and permitting of a widening'or narrowing of theentire structure as desired by the substitution of longer orshortercross beams 7 and correspondingly I provide a series of three ormore sets of spaced-blades 11 mounted on theunder side of the crossbeams 7 and consisting of a series of, sectional blades '11, asillustrated in Figs. 2, 9,10 and11.On the under side ofthe lon- 1gitudinal beams l and3, I providesuitable spaced runners 12, ofwhichthereare four on each beam, these runners preferably being provided withsuitable metal shoes 13, asil 'I' also provide-reinblades 24, asillustrated in Figs. 17 and 18, bolted to plates 14, positioneddiagonally to discharge earth laterally from the machine. But one pairof blades 24 are in operation adfa modified form f e nce blade angle;

a Like numerals designate like parts in each 7 jac-ent each cross beam,the; blades 24 being reversed according to the direction of travel ofthe machine, and arranged to slant rearwardly as shown to dischargeloose material to the outside of the machine.

At each end of the machine, bolted to the respective longitudinal beams1, 2 and 3, I

rovide drag hooks 15 to which the chains 16 may be attached. Thelongitudinal beams 1, 2 and 3 preferably are made in two sections asshown in Figs. 1 and 3 of the drawings; one of the sections of each beamhaving a reduced end 18, while the mating section has a reduced end 19,as shown in side elevation in Fig. 3, this portion of the beams beingrein forced by the beam splices 25 which are secured to the beams by thebolts '20. Beams 1 and 3 are provided with the recesses 21 to receivethe reduced ends. 10 of the cross, beams 7. The beams are also providedwith the recesses or counter-sunk portions 22 to receive the diagonalplates 14.

It will be noted that the reinforcing bars 8 are provided with aplurality of apertures for bolts. and that likewise the metal housings 9are provided with a multiplicity of apertures 28 whereby verticaladjustment of the beams 7 and of the scraper blades 11 carried by saidbeams is made convenient and practicable. It will also be noted that thescraper blades 11 are made in sections as shown in Figs. 9. 1.0 and 11.and they may be adjusted as to length of the entire scra er blade so asto adiust the machine not only to any crown or curvature of the road,but also to roads of different widths.

It will also be noted that as the machine is provided with drag hoo rsat each end.'it is not necessary to turn the machine around.

but that the tractive element-whether horses or tractor can be detachedfrom one end and hitched to the other readily.

Heretofore. road machines in general have been provided with a singleblade and if it misses it is necessary to drive back over a holeseveral. times to fill it. With this machine each of the series of threeblades wil function to perform the work. The blades are adjusted to cutat successively deeper depths from forward to rear end of the machine. a

It will also be noted that the runners are spaced from each other. beingarran ed alternately with the cross blades so that the dirt can pass outlaterally from the machine, a ssisted by the diagonal clearance blades24. The blades 11 are made in sections of two feet each, thusfacilitating, adjustment to the curve and width-of the road. Many roadsare only fourteen feet wide; some eighteen, and some twenty; and thisdiiference in width of roads is taken care of by the adjustability ofthe blades on my machine. The machine, as will be notedfrom thedrawings, has all of its partsbolted together, so that it can be quicklydisconnected for trans portation from one section of the country toanother.

It is also within the contemplation of my invention to provide wheels011 which the frame of the machine may be mounted, the wheels beingaflixed to the frame so that they can be raised or detached.

It will also be noted that the blades can be used as acutting edge or asa drag. The machine can be constructed of wood or metal.

WVhat I claim is 1. In a road machine, the combination of longitudinalbeams, a plurality of cross beams, hollow metal housings in which theends of "the cross beams are mounted, said housings being adjustablyfastened to the longitudinal beams to thereby permit of verticaladjustment of the cross beams.

2. In a road machine, the combination of longitudinal beams, a pluralityof cross beams, hollow metal housings in which the ends of the crossbeams are mounted, said housings being adjustably fastened to thelongitudinal beams to thereby permit of ver tical adjustment of thecross beams, and

scraping blades fastened to the cross beams.

3. In a road machine, the combination of longitudinal beams, a pluralityof cross beams, the cross beams having reduced ends, metal housingsadjustably bolted to the longitudinal beams and to which the reducedends of the cross beams are bolted to permit of vertical adjustment ofthe cross beams, sectional scraper blades mounted on the under side ofthe cross beams, and angle iron clearance blades mounted on the outerlongitudinal beams to discharge material.

4. In a road machine, the combination of longitudinal beams, a pluralityof cross beams securely fastened to the longitudinal beams, a series ofscraper blade sections bolted to each of the cross beams each of thescraper blade sections having a series of spaced apertures for bolts topermit of adjusting the blades to the width of the road and to provide aplurality of spaced scraping elements for the machine, the cross beamsbeing adjustably mounted relative to the longitudinal beams to permit ofvertical adjustment of the entire set of scraper blades carried by eachcross beam, and short runners mounted on the longitudinal beams andspaced between the scraper blades to permit of discharge of the materialin the space between the runners.

anee blades mounted on the outer longitudinal beams to dischargematerial, and short runners mounted on the longitudinal beams andspaced'between the scraper blades to pernut of discharge of the materialin the space between the runners.
